The value of x is [tex]x=-1[/tex]
Explanation:
The given expression is [tex]18+8 x=-x-3(1+4 x)[/tex]
We need to find the value of x.
To determine the value of x, let us solve the expression for x.
Multiplying the term 3 within the bracket, we have,
[tex]18+8 x=-x-3-12 x[/tex]
Simplifying, we get,
[tex]18+8 x=-13x-3[/tex]
Adding both sides of the expression by 13x, we have,
[tex]18+21x=-3[/tex]
Adding both sides of the expression by 18, we get,
[tex]21x=-21[/tex]
Dividing both sides of the equation by 21, we get,
[tex]x=-1[/tex]
Thus, the value of x is [tex]x=-1[/tex]
